Products classified under HTS 8112.41.10.00
Rhenium Medical Imaging Foil Scrap
Quality rejects and trim scrap from rhenium foil used in CT scanner anode targets. Under HTS 8112.41.10.00 as rhenium waste and scrap from medical device production. Recovered for high-purity refoil production.
Rhenium Catalyst Waste
Spent rhenium-impregnated catalyst residues from petroleum refining processes, containing recoverable rhenium metal. Classified under HTS 8112.41.10.00 as waste and scrap of rhenium due to its primary rhenium content exceeding other metals and being unsuitable for direct use. This scrap is typically recycled to extract rhenium for reuse in high-performance alloys.
Spent Rhenium Filament Scrap
Discarded rhenium wire filaments from mass spectrometer ion sources, broken and contaminated with trace elements. HTS 8112.41.10.00 applies as rhenium waste and scrap suitable for remelting and purification. Primarily sourced from laboratory and analytical equipment decommissioning.
Rhenium Jet Engine Clippings
Precision clippings and grindings from rhenium-containing single-crystal turbine blades for military aircraft engines. Classified as rhenium waste and scrap under HTS 8112.41.10.00 due to high rhenium recovery value. These scraps undergo vacuum remelting for reuse in high-temperature applications.
Rhenium Plating Bath Sludge
Precipitated sludge from electroplating baths using rhenium salts for corrosion-resistant coatings on valves. HTS 8112.41.10.00 covers this as rhenium waste and scrap where metallic rhenium precipitates dominate. Recovered via roasting and reduction processes.
Discarded Rhenium Thermocouple Wire
Burnt-out thermocouple wires alloyed with tungsten-rhenium for high-temperature furnace monitoring, now as scrap. Under HTS 8112.41.10.00 as rhenium waste and scrap due to significant rhenium content for recovery. Common in semiconductor and glass manufacturing.
Rhenium Electronics Contact Scrap
Stamped-out contact points from rhenium-iridium alloys used in high-reliability telecommunications switches. HTS 8112.41.10.00 for rhenium waste and scrap from precious metal contact fabrication. Recycled into new contact materials.
Rhenium Vacuum Tube Filament Scrap
Scrap filaments from specialty vacuum tubes used in microwave power amplifiers, containing pure rhenium wire. Classified HTS 8112.41.10.00 as rhenium waste and scrap from electronics manufacturing. High purity enables direct remelting.
Rhenium Sputtering Target Scrap
Edge trimmings and spent centers from pure rhenium sputtering targets for thin-film deposition in semiconductors. HTS 8112.41.10.00 as rhenium waste and scrap with >99% purity suitable for target remaking. Essential for microelectronics manufacturing.
Rhenium Superalloy Scrap
Machining turnings and clippings from nickel-rhenium superalloys used in turbine blades, with rhenium as the key recovery element. Falls under HTS 8112.41.10.00 as rhenium waste and scrap since rhenium content defines its value despite alloy form. Recovered for aerospace and jet engine manufacturing.
